BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a fastener for laying pipeswhich is used for laying respective types of pipe such as service waterpipes, gas pipes, cooling pipes and heating pipes from a ceiling,hereinafter, it may be abbreviated as a piping fastener.

[0003] 2. Description of the Prior Art

[0004]FIG. 11 shows a general fastener for laying pipes which isconventionally widely used.

[0005] The fastener shown in FIG. 11 is used for hanging, suspending orsupporting a pipe 8 from a ceiling. In this type of the fastener, a turnbuckle 3 which is used to adjust the height or position of the fastenerthrough adjusting position of a nut 2 to the hanger bolt 1 which issuspended from an anchor fixed to the ceiling, and with the result thathalf bands 5A, 5B for grasping the pipe is fixed to leg portions 3A and3B of the turn buckle 3 which is suspended and fixed. That is, both endsof the half bands 5A, 5B which are assembled by a hinge mechanism 4 insuch a manner that the bands can be freely opened and closed, and whichis separated at the right and left are fixed to the bolt 6 and the nut 7thereby supporting the pipe 8. In the actual work, first, the hangerbolt 1 is attached on the anchor on the ceiling, and subsequently, thepiping is attached on this anchor.

[0006] At the time of attaching the piping, after the nut 7 is loosenedand detached from the bolt 6, and the half band 5B is opened with ahinge mechanism 4 as shown by a dashed line, the pipe 8 is arranged onthe inside of the other half band 5A. Thereafter, work is performed forbringing back the detached half band 5B, and fixing the end of this halfband 5B to the end of the other half band 5A with the bolt 6 and the nut7.

[0007] At the time of grasping the pipe 8, the half band 5B is alreadyset in a state shown by an imaginary line wherein the half band 5B isopened from the bolt 6 and the nut 7. Thus, the half band 5B is rotatedfrom the state shown by the imaginary line to the state shown by a solidline while grasping the pipe 8 by half band 5A with the result that acircular hole at the end of the half band 5B is inserted into the end ofthe bolt 6 followed by attaching and fixing the nut 7 to the end of thebolt 6.

[0008] The above type of the piping fastener having a turn buckle asshown in FIG. 11 cannot be used, in a case where the position of thepiping approaches from the ceiling. That is, it is very difficult toperform fixing with the bolt 6 and the nut 7 in a slight gap between thepiping and lower part of the ceiling.

[0009] As a technique for solving the above-mentioned problem, a pipingfastener having a structure in which an attachment portion to the hangerbolt 1 is provided at the center of the side of one of the half bands 5Aand 5B having a half-divided ring-like configuration is described inRegistered Utility Model Publication No. 3058296, Unexamined PatentPublication No. H10238660, Unexamined Patent Publication No. H11-182743and the Patent Gazette (National Publication of Translated Version) No.2000-513084.

[0010]FIG. 12 shows the piping fastener described in the above-mentionedRegistered Utility Model Publication No. 3058296. This piping fastenerhas a structure in which the half bands 5A and 5B are integrallyconnected by the hinge mechanism 4, and the half band 5A is attached tothe hanger bolt 1 at the attaching position which is settled on the sideof the half band 5A, thereby attachment to an anchor (such as anembedded nut or the like) is directly fixed to a ceiling or the likewithout intervention of the turn buckle as shown in FIG. 11.

[0011] In the piping fastener shown in the above-mentioned JapaneseUtility Model No. 3058296, since the half bands 5A and 5B are fixed eachother on the side position of the pipe 8, the work of fixing the bolt 6and the nut 7 is difficult despite the presence of a space which allowsthe hands of a worker to be inserted in the sidewise direction of thepipe 8. That is, since the bolt 6 and the nut 7 are free elements whichare separated from and independent of the half bands 5A and 5B, when thenut 7 is detached so as to grasp the piping, it often leads to thedetachment of the bolt 6 because of vibration at the time of the work,further, a worker may drop the detached nut 7.

SUMMARY OF THE INVENTION

[0012] The present invention has been made in view of theabove-mentioned problems. Therefore, a first object of the presentinvention is to provide a fastener for laying pipes which enables layingpipes by a simple work. A second object of the present invention is toprovide a fastener for laying pipes which has mechanism preventing todetach nuts and bolts from the bands.

[0013] The inventor of the present invention have continued research ona fastener for laying pipes for solving the above-mentioned problems andhave found that the projection portion becomes an obstacle in a casewhere a spatial allowance below the pipe is small or the head is bumpedagainst the projection portion during work, when the mechanism forfixing the bands is projected in a downward direction. In particular,when the ceiling is low or when the piping position is low or the like,it has been found that there is a fear that the head or the shoulder iscontacted when the work is done under the pipes or when the workerpasses under the pipes Then, as disclosed in the above-mentionedregistered Utility Model Publication No. 3058296, the inventor of thepresent invention has considered the formation of a structure which isnot projected in a downward direction by the location of the mechanismfor fixing the bands at the center of the side portion from below.However, in this case, it has been found that the projection portionbecomes an obstacle when other pipes and wiring are required to bearranged side by side with each other, or the projection portion becomesan obstacle when it is required to arrange the pipes at a location wherethe pipes come into contact with the wall and the like.

[0014] A third object of the present invention is to provide a fastenerfor laying pipes which can be arranged at a construction site wherespatial allowance is small on the side of the pipes or below the pipesand which takes into consideration safety at the time of work.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0029] Details of the present invention will be explained according tothe accompanied drawings.

[0030] First, according to FIGS. 1 to 4, a first embodiment 4 will beexplained. In FIG. 1, FIG. 1-A shows a front view, FIG. 1-B a planeview, FIG. 1-C a left side view, FIG. 1-D right side view and FIG. 1-E abottom view.

[0031] This first embodiment has the following structure; a band 10 isformed in a ring-like configuration with a material having elasticitysuch as a thin plate metal such of as stainless steel or the like andsoft synthetic resin. The top portion of the band 10 is bent to preparean attachment portion 12 on which a penetration hole 11 is formed for abolt 20 which is used for screwing to the anchor 21 provided on theceiling. Then, open ends of the band 10 are bent to form bent portions13 and 13 on which penetration holes are provided for inserting bolts 14respectively, and bolts 14 and nuts 15 are arranged. These bolts 14 andnuts 15 constitute a mechanism for fixing the open ends of the band 10,and this fixing mechanism and the bent portion 13 are provided on thelower end of the band 10.

[0032] Preferably, the band 10 is formed by using stainless steel suchas SUS430 (a designation of the Japan Industrial Standard=JIS) or thelike. Although the band 10 has elasticity as a whole, the band 10 has tobe opened largely at the time of grasping the pipes 22, so that the bentportions formed on bases of the attachment portion 12 constitutes bentsupport points S1 and S2 (see FIG. 2-A).

[0033] At the time of the actual work of laying pipes, as shown in FIG.2, a bolt 20 is inserted into the penetration hole 11 of the attachmentportion 12. This bolt 20 is screwed to the anchor 21 provided on theceiling. Further, means for fixing the attachment portion 12 to theceiling is not limited to a configuration of anchors and bolts as shown.

[0034] In order to fasten the pipe 22 to the fastener, as shown in FIG.2, first, the nut 15 is loosened to detach from the bolt 14, and lowerends of the band 10 are largely opened (see FIG. 2-A). The pipe 22 ispushed into an inside space of the band 10 through the open space formedby both ends of the band 10, and then the band 10 is returned to theformer figure such as a ring-like configuration by using elasticity ofthe band 10 thereby fixing the bolt 14 and the nut 15 (see FIG. 2-B).

[0035] As described above, in the conventional fastener, as shown inFIGS. 11 and 12, the bolt 14 and the nut 15 constitute free elementswhich can be separated from and independent of the band 10, so that thedetachment of the nut 15 may lead to detachment of the bolt 14 from thepenetration hole at the bent portion 13 of the end of the band 10.Consequently, in this structure, a structure is desired in which work isperformed for engaging the nut 15 again to the bolt 14 to be fastened bydetaching the nut 15 from the bolt 14 and arranging the piping 22 byopening the band 10 in consideration of the fact that the bolt and thenut are not detached therefrom.

[0036] Therefore, in the present invention, in order to solve theinferior usage described above, a mechanism for preventing detachment ofthe bolt and/or the nut is adopted in association with the mechanismsfor fixing the ends of the band.

[0037] As an example of a mechanism for preventing the detachmentthereof, a structure in which only the bolt is prevented from beingdetached (claim 10), a structure in which only the nut is prevented frombeing detached (claim 11), a structure in which the detachment of boththe bolt and the nut are prevented, the nut is fixed with soft caulkingof the nut or collar portion of the nut to the band in a rotatablemanner, and the bolt is fixed with hard caulking, welding, bonding orthe like to the band in an unrotatable manner (claim 12), and astructure in which the detachment of both the nut and bolts isprevented, the nut is fixed with hard caulking, welding, bonding or thelike to the band and the bolt is fixed with the bolt fixing means in arotatable manner (claim 13).

[0038]FIG. 3 shows five examples to fix the bolt to the band bymechanisms for preventing the detachment. That is, as shown on FIG. 3,the bolt 14 is fixed to one of the bent portion 13 on one side of theband 10, and then the nut 14 is prevented from detaching even when thenut is detached. When specifically explained, the embodiment includes aform in which the head portion of the bolt 14 is caulked to the bentportion 13 of the band 10. (see FIG. 3-A) This form includes a form inwhich the bolt 14 is tightly caulked so that the bolt 14 does not runidle), a form (see FIG. 3-B) in which the bent portion 13 of the band 10is sandwiched with a fixture such as a clip or the like for engagingwith the head of the bolt 14 and the bolt 14, a form (see FIG. 3-C) inwhich the bolt 14 is welded or bonded to the bent portion 13 of the band10, a form (see FIG. 3-D) in which the head of the bolt 14 is welded orbonded to the bent portion 13 of the band 10, and a form (see FIG. 3-E)in which the bolt 14 is fixed with a independent thin nut 14 a. Out ofthese forms, fixing with caulking as shown in FIG. 3-A, fixing with afixture such as a clip or the like as shown in FIG. 3-B, and two formsof fixing with a thin nut 14 a shown in drawing 3-E in FIG. 3, therotation of the bolt is disabled in a case of tight fixing and therotation of the bolt becomes free in the case of soft fixing whileenables correspondence to either of claim 12 and claim 13.

[0039]FIG. 4 shows two examples to fix the nut to the band end bymechanisms for preventing the detachment. FIG. 4-A shows a form in whichthe nut 15 is fixed rotatably to the bent portion 13 of the band 10 by asoft caulking. FIG. 4-B shows a form in which the nut 15 is fixedunrotatably to the bent portion 13 of the band 10 by a hard caulking.The fixing method of the nut 15 is not limited to the above caulkingmethod. As described above, the nut may be fixed through welding andbonding or other known means, and a nut having a collar portion can beused.

[0040] In the above mentioned first embodiment, the band 10 is formed ina ring-like configuration with sheet material having elasticity, andattachment portion 12 having a penetration hole 11 is prepared on thetop portion thereof. However, the present invention is not limitedwithin the above mentioned structures. For example, a turn buckle can beused in place of the attachment portion 12. In this case, as shown inFIG. 10, the top position of the fastener is fixed to the hanger bolt bythe bolt and nut through the turn buckle which are vertically providedfrom an anchor such as a ceiling or the like (claim 5).

[0041] In the case of this embodiment, the band 10 is formed by a pairof belt-like metal each of which is formed into a ring-likeconfiguration, and each upper end of the band is bent to form apenetration hole for fixing the turn buckle, and the bent portions 13and 13 are formed on the lower ends of the respective bands. Thestructure of the turn buckle and attachment portion of the band 10 arethe same as the turn buckle 24 and attachment portion 17 of the band 10as shown in FIG. 10.

[0042] Next, according to FIG. 5, the second embodiment shown in claim 7will be explained.

[0043] In this second embodiment, the fastening mechanism is provided onthe left end of the ring-like band 10. As described above, in the firstembodiment, the same fastening mechanism is provided on the lower end ofthe ring-like band 10. In the case of the second embodiment, theposition of the fastening mechanism is not limited to the left end ofthe band 10 shown in FIG. 5. The position thereof may be the right end.The position may be appropriately determined in accordance with thesituation such as the position of the pipes, other pipes and wiringarranged side by side, or the like.

[0044] In the second embodiment as well, the detachment preventingmechanism (claims 9 to 13, FIGS. 3 and 4) which is the same as the firstembodiment can be adopted. Furthermore, with respect to the attachmentportion 12, the turn buckle 24 and attachment portion 17 shown in FIG.10 described later in the same manner as the first embodiment can beconstructed.

[0045] According to FIGS. 6 to 9, the third embodiment set forth inclaim 8 will be explained.

[0046] In the third embodiment, the bolt 14 and the nut 15 as a memberof the fixing mechanism of the band are fixed through the fixingmechanism comprising a structure for preventing the detachment from thebent portion 13. As shown in FIG. 7, in this structure, the bolt 14 isprevented by a clip 16 to detach from the nut 15, which is caulked tothe bent portion 13. Further, in this third embodiment as well, astructure identical to the first embodiment and second embodiment,namely, a fixing portion is adopted which is provided with a mechanism(claims 9 to 13, FIGS. 3 and 4) for fixing and preventing the detachmentwith a normal bolt and nut.

[0047] As shown in FIG. 6, this third embodiment is characterized inthat the bent portion 13 and the fixing mechanism (comprising the bolt14 and the nut 15) are provided at a position between the lower end andleft end (or the right end), and is provided inside of a space portionformed with a horizontal line X contacting a lower end of the ring-likeband 10 and a vertical line Y contacting a left end of the ring-likeband 10 (or a vertical line Y′ contacting the right end), and aring-like portion of the band 10.

[0048] As a specific position, the above-mentioned bent portion 13, andthe bolt 14 and the nut 15 are provided at a position within a range of90° through 180° when the center of the attachment portion 12 is set to0° or 360°, and at a position at which the bent portion 13 projectingfrom an outer circumference of the band 10, and the bolt 14 and the nut15 have a size which allows accommodation inside of the horizontal lineX and the vertical line Y (or a vertical line Y′). In particular, apreferable position is a position of 135° (or a position of 225°).

[0049] As described above, in the present invention, there is noprojection portion to the sidewise and lower direction of the band,because the bent portion 13 and the fastening mechanism (comprising thebolt 14 and the nut 15) are provided inside of a space formed of ahorizontal line X contacting the lower end of the band 10, the verticalline Y contacting the ring-like left end (or a vertical line Y′contacting the right end), and a ring-like portion of the band 10.Consequently, pipes can be laid even in the case where spatial allowanceis small on the side of the pipes and below the pipes. Besides, it ispossible to prevent accidents such as bumping a head or a shoulderagainst the projection portion at the time of work at a position belowthe pipes and at the side of the pipes.

[0050] At the time of actual work of laying the pipes, as shown in FIG.8, first, a bolt 20 is inserted into the penetration hole 11 which isprepared at the center of the attachment portion 12, and this bolt 20 isconnected to an anchor 21 which is attached to the ceiling. Further, ameans for fixing the attachment portion 12 to the side of the ceiling isnot limited to a structure comprising the anchor and the bolt as shown.

[0051] In order to attach the pipes 22, first, the bolt 14 is loosened,and is detached from the nut 15, and the end of the band 10 is opened.Next, the end of the band 10 is largely opened (see FIG. 8). At thistime, the band 10 has elasticity as a whole. At the time ofincorporating the pipe 20, the end of the band 10 must be largelyopened. Thus, the end of the attachment portion 12 constitutes bendingsupport points S1 and S2 while the band 10 as a whole is flexiblyenlarged and opened. Then, the pipe 22 is pushed into the inside spaceof the band 10 from the open space which is largely opened. Then, theband 10 is brought back to form a ring-like configuration by usingelasticity of the fastener, the bolt 14 and the nut 15 are fastened toprovide a construction completion state shown in FIG. 9.

[0052] As explained above, the fastener for laying pipes according tothe third embodiment of the present invention has a structure in whichone sheet of a belt-like member is formed into a ring-like configurationwith elastic material to form a band 10, and an attachment portion 12providing the penetration hole 11 for the bolt. However, the presentinvention is not limited thereto, for example, as shown in FIG. 10, inthe place of the attachment portion 12 on the top portion of the band10, an attachment structure comprising the bolt 25 and nut 26 which isused to fix the bento portions 17 and 17 the turn buckle 24 which isattached to the hanger bolt 23 which is vertically suspended from theanchor of the ceiling (claim 5). In the case of this embodiment, thereis provided a structure in which a pair of belt-like bands 10 and 10 areformed into a ring-like configuration with elastic material, both upperends of the band 10 are bent to form the bent portions 17 and 17 havinga penetration hole for the bolt 25 to fix the ends of the band 10 to theleg portion of the turn buckle 24, and the bent portions 13 and 13 areformed on the each ends of the bands 10 and 10.

[0053] The mechanism for fixing the band of the present invention can beapplied to the fastener of suspension type (see FIG. 13) and fastener ofstand type (see FIG. 14). Hereinafter, this point will be explainedbelow.

[0054] That is, as shown in FIG. 13, the mechanism can be applied to thefastener of the suspension type in which the attachment portions 17 and17 formed on the both ends of the band 10 are fixed to the leg portionsof the turn buckle 24 attached to the lower end side of the hanger bolt23 having one end fixed to the ceiling slab with the bolt 14 and the nut15. The leg portion at least on one side of the turn buckle 24 and theattachment portion 17 of one of the bands 10 and 10 are connected withcaulked nut 15. This nut 15 is fixed in an unrotatable state while thebolt 14 is attached to the other attachment portion 17 of the other band10 in a state of preventing detachment with a clip 16 for preventing thedetachment of the bolt or in a freely rotatable state.

[0055] Furthermore, as shown in FIG. 14, the mechanism can be applied tothe fastener of stand type which is attached to a stand 28 fixed to thewall surface, the floor or the like, and which is supported in such amanner that the pipe 22 is grasped with a pair of band 10 which areintegrated with the hinge mechanism 27 (a set mechanism is alsosufficient). On the attachment portion 17 which comprises the end of theband 10 on one side, two bolts 14 are attached in a state in whichdetachment of the two bolts 14 is prevented with clips 16 and 16 forpreventing detachment, and the bolts 14 and 14 can be freely rotated. Onthe attachment portion 17 which comprises the end of the other band 10,two nuts 15 and 15 are caulked.

[0056] According to the present invention, the following technicalimprovements can be obtained.

[0057] First, in the first and second embodiments of the fastener forlaying pipes according to the present invention, pipes can be laid evenat a position where the pipes are laid in the vicinity of the ceiling.Even when the nut is detached and the bolt is not dropped, the usage isfavorable. Furthermore, the belt-like band is formed in a ring-likeconfiguration with elastic material, and the bent portion may only beprovided on the end and the attachment portion may be provided on thecentral portion of the band. Consequently, as compared with a structure(see FIGS. 11 and 12) in which the two bands are connected with thehinge mechanism, the present invention has an advantage in thatmanufacture is simple, and manufacturing costs are inexpensive.

[0058] According to the third embodiment of the present invention, thereis provided a structure in which the bent portion and the fixingmechanism is provided inside of the horizontal line contacting the lowerend of the fastener, and the vertical line contacting the ring-like leftend or the right end. Consequently, the projection portion in a sidewisedirection or in a downward direction of the band can be eliminated. Evenin a case where spatial allowance is small on the side of the pipes orbelow the pipes, the pipes can be laid. Furthermore, it is possible toprevent accidents such as bumping of a head and a shoulder against theprojection portion at the time of work at a position below the pipe orat the side of the pipe. Consequently, the fastener for laying pipes canbe provided which enables laying pipes even in the case where thespatial allowance is small on the side of the pipes and below the pipesand which takes into consideration safety at the time of work.
